Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the priority of Republic of China
Patent Application No. 102110402 filed on Mar. 25, 2013, in the
State Intellectual Property Office of the R.O.C., the disclosure of
which is incorporated herein by reference
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The invention relates to an optical transceiver device,
particularly to an optical transceiver device transmitting
electrical signal and control signal in different signal
channels.
[0004] 2. Descriptions of the Related Art
[0005] With the rapid development of network communication, the
bandwidth and speed of network transmission keep on increasing. The
conventional cooper cables used for signal delivery are replaced by
optical cables gradually. Compared to conventional cooper cables,
the optical cables not only are advantageous of small volume and
EMI (electromagnetic interference) exemption, but also provide
rapid and lots of signal transmission. Thus, the optical fiber
network technology using optical cables as signal delivery media is
widely applied to communication between various industries or
equipments.
[0006] Because of convenience provided by networks, people rely
more and more on networks. Therefore, a sudden network
disconnection results in larger and larger loss for people. In an
optical fiber network, an in-line equipment has to deliver signal
by an optical transceiver device and an optical network equipment.
The optical transceiver device is provided with an O/E converter.
The O/E converter may convert electrical signal of the in-line
equipment into optical signal and deliver to the optical network
equipment, and may convert optical signal of the optical network
equipment into electrical signal and send to the in-line equipment.
As such, the communication between the in-line equipment and
optical network equipment is accomplished. The in-line equipment
normally needs to be arranged with one single optical transceiver
device for normal connection to the optical fiber network. However,
some in-line equipments, which are used to provide data filtering
and/or flow control functions, need to be arranged with two optical
transceiver devices for connection with two optical network
equipments. As one of the optical transceiver devices receives
optical signal from one of the two optical network equipments, only
after passing through the in-line equipment can the optical signal
be output to the other optical network equipment from the other
optical transceiver device. As such, once said in-line equipment
loses electrical power or is down, the signal transmission between
the two optical network equipments would be enforced to stop and
thus the disconnected network communication occurs.
[0007] As the in-line equipment connecting two optical transceiver
devices as mentioned above runs abnormally, the two optical
transceiver devices will usually be connected in a manual manner in
order for the two optical network equipments to recover smooth
network communication such that the damage due to network
communication disconnection for users may be reduced. However, the
manual manner cannot solve effectively the problem of unclear
communication disconnection, which is a severe problem argued by
general insiders, between optical network equipments because it is
time consuming and prone to make errors.
[0008] In view of this, it is the problem that those skilled in the
art are urgent to solve about how to provide an optical transceiver
device to solve the problem of optical fiber network disconnection
as the in-line equipment runs abnormally.
SUMMARY OF THE INVENTION

determined direction. The optical transceiver device further
includes multiple vibration absorbers provided separately on two
end surfaces of said optical switching switch toward said

[0014] Preferably, the O/E conversion substrate further may have a

in order to provide an clamping force for the first O/E converter
unit or second O/E converter unit to abut the settling frame.
[0015] The switch control substrate may be further extended with a
circuit flange plate in order to achieve the electrical connection
between the switch control substrate and the optical switching
switch. But, the connected electrically between the switch control
substrate and the optical switching switch may further be achieved
by a flexible circuit board or other electrical connection manners.
Multiple blade stoppers may be protruded separately at different

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0033] Embodiments of the present invention will now be described
in detail with reference to the accompanying drawings. The
invention may, however, be embodied in many different forms and
should not be construed as being limited to the embodiments set
forth herein. Rather, these embodiments are provided so that this
disclosure will be thorough and complete, and will fully convey the
scope of the invention to those skilled in the art. In the
drawings, the shapes and dimensions of elements may be exaggerated
for clarity, and the same reference numerals will be used
throughout to designate the same or like components.
[0034] Refer to FIG. 1, it is a circuit block diagram showing a
first implementation of the optical transceiver device according to
the invention. As shown in FIG. 1, the optical transceiver device 1
of the invention is used to connect separately a first, a second
optical network equipment 2, 3 and an in-line equipment 4 to
establish an optical fiber network for the in-line equipment 4 to
be able to provide the first, second optical network equipment 2, 3
with functions such as, for example, data filtering and/or flow
control etc. In addition, the optical transceiver device 1 may also
execute a bypass mode to guarantee normal network communication
preserved for the first and second optical network equipments 2, 3
as the in-line equipment 4 runs abnormally.
[0035] The optical transceiver device 1 of the invention mainly
includes a device housing, an optical transceiving component 12, an
O/E conversion substrate 13, an optical switching switch 14, and a
switch control substrate 15. The optical transceiving component 12
has a connection structure of a first optical transceiving port 121
and a second optical transceiving port 122 for connecting
separately the first, second optical network equipment 2, 3 to
provide a delivery path of optical signal, such that the optical
signal from the first, second optical network equipment 2, 3 may be
received, or the optical signal inside the optical transceiver
device 1 may be delivered separately to the first, second optical
network equipment 2, 3.
[0036] The O/E conversion substrate 13 has an electrical signal
port 131 exposed to a first location of the device housing 11 for
plugging the in-line equipment 4 and connecting electrically with
the in-line equipment 4 as a channel for electrical signal delivery
between the optical transceiver device 1 and the in-line equipment
4. The O/E conversion substrate 13 further has a first O/E
converter unit 132 and a second O/E converter unit 133. The first,
second O/E converter unit 132, 133 may convert separately the
optical signal received from the first, second optical transceiving
port 121, 122 into electrical signal, or the electrical signal
received from the in-line equipment 4 into optical signal. The
first O/E converter unit 132 and the second O/E converter unit 133
are formed by, for example, a transmitter optical sub-assembly
(TOSA) and a receiver optical sub-assembly (ROSA), or other O/E
transceiving elements.
[0037] The optical switching switch 14 is connected separately with
the first, second optical transceiving port 121, 122 and the first,
second O/E converter unit 132, 133, and may provide a channel for
optical signal delivery. The optical switching switch 14 of the
invention may select various optical switch elements, such as
Dual2.times.2 half duplex optical switch element, Dual2.times.2
full duplex optical switch element or 4.times.8optical switch
element. The switch control substrate 15 is connected electrically
with the optical switching switch 14 and has a control signal port
151. The control signal port 151 is exposed to a second location of
the device housing 11 for plugging the in-line equipment 4 and
connecting electrically with the in-line equipment 4 in order to
receive control signal sent by the in-line equipment 4 to the
optical switching switch 14 through a control signal sending unit
41. The switch control substrate 15 may, according to the control
signal received by the control signal port 151, order the optical
switching switch 14 to change running state, making the optical
switching switch 14 running a normal mode, allowing the first,
second optical transceiving port 121, 122 to communicate optical
signal with the first, second O/E converter unit 132, 133 through
the optical switching switch 14 separately; or order the optical
switching switch 14 to run a bypass mode for mutual delivery of
optical signal of the first, second optical transceiving port 121,
122 through the optical switching switch 14 without the in-line
equipment 4 to implement delivery of optical signal between the
first, second optical transceiving port 121, 122.
[0038] Here, it is noted that the optical switching switch 14 may
be, for example, a locking optical switch element, and may also be,
for example, a non-locking optical switch element. As the optical
switching switch 14 is a non-locking optical switch element, when
the above control signal sending unit 41 needs to send control
signal carrying control instruction to the optical switching switch
14 through the control signal port 151, if the control signal and
the electrical signal between the optical transceiver device 1 and
the in-line equipment 4 are transmitted on the same or adjacent
channels for long time, inductive effect will occur between the
control signal and electrical signal to result in mutual
interference and very large impact on signal transmission quality.
Thus, in the optical transceiver device of the invention, the
electrical signal port 131 and the control signal port 151 are
configured in different locations, that is, the transmission
channels of control signal and electrical signal are configured
separately. As such, the inductive effect, which results in the
problem with respect to mutual interference of signal, generated by
transmission of different signal on the same or adjacent channels
may be avoided.
[0039] As shown in FIG. 12, the O/E conversion substrate 13 further
has a settling frame 134 and a spring clip 135. The first, second
O/E converter unit 132, 133 may enter the settling frame 134
separately through openings of two side walls of the settling frame
134, and abut the two side walls of the settling frame 134. Further
refer to FIG. 11, one side of the spring clip 135 may contact a
wall of the settling frame 134, and the other side of the spring
clip 135 may contact the first O/E converter unit 132 or second O/E
converter unit 133 in order to provide clamping force for the first
O/E converter unit 132 or the second O/E converter unit 133 to
adjoin the settling frame 134.
[0040] The control manner and time of the in-line equipment 4 for
the optical switching switch 14, and various operation modes of the
optical switching switch 14 are exemplified as following:
[0041] As the in-line equipment 4 runs from abnormally (the
abnormal running indicates that the in-line equipment 4 is down or
loses electrical power) to normally, control signal may be sent to
the optical switching switch 14 through the control signal sending
unit 41 to order the optical switching switch 14 to run in the
normal mode for the first, second optical transceiving port 121,
122 to communicate with the optical signal of the first, second O/E
converter unit 132, 133 separately. At this moment, the optical
signal of the first, second optical network equipment 2, 3 may be
delivered separately to the first, second O/E converter unit 132,
133 through the first, second optical transceiving port 121, 122,
the optical switching switch 14 in order, and thereby is converted
into corresponding electrical signal for the in-line equipment 4 to
process. It is noted additionally that the first, second O/E
converter unit 132, 133 may also convert the electrical signal
provided by the in-line equipment 4 into corresponding optical
signal, and deliver to the first, second optical network equipment
2, 3 through the optical switching switch 14, the first, second
optical transceiving port 121, 122 in order.
[0042] Moreover, as the in-line equipment 4 runs from normally to
abnormally, the optical switching switch 14 may run in the bypass
mode. In executing bypass mode, the optical switching switch 14
will disconnect the communication of optical signal between the
first, second optical transceiving port 121, 122 and the first,
second O/E converter unit 132, 133 for the first, second optical
transceiving port 121, 122 to communicate with each other and
transmit optical signal mutually to form an optical bypass effect.
Thus, although the in-line equipment 4 stops operation, the optical
signal of the first, second optical network equipment 2, 3 may
still deliver with each other through the first, second optical
transceiving port 121, 122 to guarantee normal network
communication between the first and the second optical network
equipments 2, 3 as the in-line equipment 4 is abnormal.
[0043] Refer to FIG. 2, which is a circuit block diagram showing a
second implementation of the optical transceiver device according
to the invention. Wherein, the same or like elements as the optical
transceiver device of the above implementation (as shown in FIG. 1)
are indicated by the same or like element numerals, and the
description thereof are omitted in order for clearer understanding
of the application.
[0044] The largest difference between the optical transceiver
device 1' of the second implementation and the optical transceiver
device 1 of the first implementation is in that, the optical
transceiver device 1' of the second implementation omits the
configuration of the optical switching switch 14 and the switch
control substrate 15, and is provided with an indication lamp 18'
and a lamp control substrate 15'.
[0045] The indication lamp 18' has a light emitting surface exposed
to a device housing; while the lamp control substrate 15' is
connected electrically with the indication lamp 18'. The lamp
control substrate 15' has a control signal port 151' exposed to a
second location of the device housing. A control signal port 151'
is provided for connecting electrically the in-line equipment 4 to
receive the control signal sent to the indication lamp 18' by the
control signal sending unit 41 of the in-line equipment 4 in order
to adjust brightness state of the indication lamp 18', thereby
indicate the running state of the first, second O/E converter unit
132, 133 for users to master the running state of the O/E converter
units in the optical transceiver device V.
[0046] It is understood from the disclosure of the above second
implementation that the optical switching switch and switch control
substrate are not necessary elements in the optical transceiver
device of the invention.
[0047] Further refer to FIGS. 3 to 14 together, which are
structural views showing the first implementation of the optical
transceiver device according to the invention. As shown in the
figures, a device housing 11 has a containing space for containing
an O/E conversion substrate 13, an optical switching switch 14 and
a switch control substrate 15. The device housing 11 further has a
top cover 111. The top cover 111 covers an open side of the
containing space in the device housing 11 in order to protect
electronic elements contained in the device housing 11. As shown in
FIG. 4, the electrical signal port 131, control signal port 151 are
exposed separately to a first, second locations on a back side wall
of the device housing 11, and may be plugged to the in-line
equipment at different locations. But, the electrical signal port
131, control signal port 151 may still be exposed to walls on other
sides of the device housing 11, instead of limited to the location
feature disclosed in FIG. 4.
[0048] A carrying frame 16 is further provided in the device
housing 11 of the optical transceiver device 1 according to the
invention, for carrying the optical switching switch 14 and switch
control substrate 15, and providing fixation for the optical
switching switch 14 and switch control substrate 15. The carrying
frame 16 further has a cantilever sheet 161 extending to be below
the optical switching switch 14. The cantilever sheet 161 extends
outside a wall of the carrying frame 16 to form a cantilever beam
structure in order for providing elastic support for the optical
switching switch 14, and reducing the vibration amplitude of the
optical switching switch 14 due to impact of external force, and
further preventing the optical switching switch 14 from damaging
due to over vibration, and further achieving the effect of
increasing the service life of the optical switching switch 14. In
addition, the optical switching switch 14 may have a vibration
absorbers 17 attached on the wall thereof close to the cantilever
sheet 161 and top cover 111 to absorb partial vibration energy of
the optical switching switch 14 by means of the vibration absorbing
property of the vibration absorbers 17. Said vibration absorber may
be a vibration absorption cotton. As such, the effect to increase
the service life of the optical switching switch 14 is achievable.
The carrying frame 16 may be further formed with a guiding surface
162 for guiding optical fibers delivering optical signal inside the
device housing 11 to extend toward a determined direction. As such,
the winding process of optical fibers inside the device housing 11
may be simplified.
[0049] Multiple blade stoppers 112 are protruded separately on an
inner wall of the device housing 11 at different height locations
for abutting and fixating the O/E conversion substrate 13 at
different height locations. The blade stoppers 112 are, for
example, tenons or seizing sheets extending toward the interior of
the device housing 11. Refer to FIGS. 8 to 10, in order to insert
the O/E conversion substrate 13 into the containing space inside
the device housing 11, at first, the O/E conversion substrate 13
has to be raised to a height location (the height location allowing
for leaving the device housing 11), and then the O/E conversion
substrate 13 is inclined toward the blade stoppers 112. Next, the
O/E conversion substrate 13 is moved toward the solid arrow
indicated in FIG. 8 until the front edge of the O/E conversion
substrate 13 abutting the inner wall of the device housing 11. As
shown in FIG. 9, subsequently, the O/E conversion substrate 13 is
moved toward the direction indicated by the solid arrow in FIG. 9
until the multiple blade stoppers 112 on the inner wall of the
device housing 11 at different heights abut separately both the
upper and lower sides of the O/E conversion substrate 13. Refer to
FIG. 10, at the moment, the fixation of both sides of the O/E
conversion substrate 13 is accomplished because of being
constrained by each of the blade stoppers 112. The relative
location relationship of the device housing 11 and the O/E
conversion substrate 13 will not change even though the electrical
signal port 131 is under removal from the in-line equipment 4.
[0050] The optical transceiver device 1 of the invention further
includes an indication lamp 18 and an optical transceiving port
socket 19. The indication lamp 18 has a light emitting surface
exposed to the device housing 11. The indication lamp 18 further
has a light emitting element 181, which may connect electrically
with the switch control substrate 15 through a circuit board. The
switch control substrate 15 may provide electrical signal to the
light emitting element 181 according to the running state of the
optical switching switch 14 and/or the first, second O/E converter
unit 132, 133, in order to adjust the brightness state of the
indication lamp 18, in order to indicate the running state of the
optical switching switch 14 and/or the first, second O/E converter
unit 132, 133 by means of brightness. In the disclosure of FIG. 13,
the optical transceiving port socket 19 is provided at the device
housing 11. The first, second optical transceiving port 121, 122
may penetrate and enter the optical transceiving port socket 19 to
accomplish fixation. The indication lamp 18 abuts the top of the
optical transceiving port socket 19. As such, the top cover 111 may
abut the indication lamp 18 as covering over the device housing 11
to provide a longitudinal downward pressure for the indication lamp
18, and further constrain the longitudinal movement of the optical
transceiving port socket 19 by the indication lamp 18, such that
the optical transceiving port socket 19 will not vibrate
easily.
[0051] In the first implementation of the optical transceiver
device according to the invention, the indication lamp 18 further
comprises multiple light guiding pillars 182 and light stoppers
183. The light stoppers 183 may be an opaque material. Each light
guiding pillar 182 corresponds to one light emitting element 181 in
order to guide the light of the light emitting element 181 to the
light emitting surface exposed to the device housing 11. One light
stopper 183 is provided between adjacent light guiding pillars 182
to block mutual delivery interference of lights between adjacent
light guiding pillars 182 by the light stopper 183, such that the
brightness state presented by the indication lamp 18 meets
expectation.
[0052] Further refer to FIG. 15, which is a structural view showing
the third implementation of the optical transceiver device
according to the invention after the device housing is omitted. The
switch control substrate 15 is further extended with a circuit
flange plate 152 in order to achieve the electrical connection
between the switch control substrate 15 and the optical switching
switch 14. But, the connected electrically between the switch
control substrate 15 and the optical switching switch 14 may
further be achieved by a flexible circuit board 153 or other
electrical connection manners, refer to FIG. 7.
[0053] In summary, the optical transceiver device of the invention
has at least the following advantages and features with technically
unexpected effects:
[0054] 1) With mutually separated transmission channels of control
signal and electrical signal, the mutual interference of different
types of signal transmitted in the same or adjacent channels is
avoided.
[0055] 2) With the structure design of spring clip, the combination
of O/E converter unit and O/E conversion substrate is achieved,
such that the O/E converter unit does not move easily due to
external force and even leave the O/E conversion substrate.
[0056] 3) The running state of the optical switching switch may be
changed according to the state of the in-line equipment to,
thereby, guarantee normal communication of the optical fiber
network formed by the first and second optical network equipments
without suffering from the impact of sudden conditions, such as
electrical power loss or machine crash of the in-line
equipment.
[0057] 4) The O/E converter unit and optical switching switch are
configured separately on the O/E conversion substrate and switch
control substrate. As such, the detection for the O/E converter
unit and optical switching switch may be performed separately to
perform rapid detection separately whether or not the O/E converter
unit and optical switching switch are normal. In addition, redesign
of switch control substrate is not necessary if the specification
or model of the O/E converter unit is to be changed. Thereby, the
design cost of substrates is reduced effectively. Similarly,
redesign of O/E conversion substrate is unnecessary if the
specification or model of the optical switching switch is to be
changed.
[0058] The examples above are only illustrative to explain
principles and effects of the invention, but not to limit the
invention. It will be apparent to those skilled in the art that
modifications and variations can be made without departing from the
spirit and scope of the invention. Therefore, the protection range
of the rights of the invention should be as defined by the appended
claims.
